Abstract: A leadframe for use in mounting and interconnecting an integrated circuit. A first or base metal layer of the leadframe comprises at least one of brass or other copper alloy. A second, conducting layer atop the base layer comprises at least one of aluminum or an aluminum alloy. A third, upper layer on the second layer comprises at least one of copper or a copper alloy. The first, second and third layers are formed into a multilayer clad strip, a portion of at least the third layer being selectively removed to expose a selected pattern of the second layer.

Abstract: A fabrication method and leadframe construction in which the leadframe is formed by selectively removing portions of a multilayer clad strip to expose a selected pattern of a conductive metal to conform to the desired application of the leadframe. The clad strip may be formed of a base layer of copper alloy, a conducting layer of aluminum or aluminum alloy, and an upper layer of copper or a copper alloy. A layer of tin or lead-tin alloy may be plated onto the upper layer.

Abstract: Solder wire attached along its length to a base metal by a small quantity of solder melted at the solder-base metal juncture.

Abstract: System for rapid preparation of an identification card comprising(a) photographing the subject with an automatic rapid development camera in which the view finder is focused offcenter to produce a photograph wherein the subject's head appears at a predetermined offcenter location;(b) placing the developed photograph between the two halves of a single folded card having a back half and a front half with a precut aperture which opens over the head of the subject in the photograph;(c) trimming the excess of the photograph that extends beyond the edges of the card; and(d) sealing the two halves and the photograph to each other to produce a three-layer laminate.

Abstract: A portable collapsible container made of flexible material the general form of a thin walled barrel, comprising a cylindrical body portion and a bottom cover removably attached to the lower end of the cylindrical wall; the body portion containing two enclosed hoop members one of which is adjacent the upper end of the cylindrical wall and the other which is spaced apart therefrom, the two hoop members being separated by a plurality of vertical stiffening members enclosed in the wall of said body portion and spaced substantially equidistantly around said wall and disconnected from both hoop members.
